A few weeks back I reached out to Tim Nolet of Checkly: https://www.indiehackers.com/product/checkly and offered to do a marketing teardown/deep-dive on his SaaS product.

I'm looking to do a couple more public teardowns on my website and eventually focus on email marketing for SaaS businesses. If you're running a SaaS with a bit of product-market fit, contact me or leave a comment.
